Current/voltage mode full-wave rectifier based on a single CCCII

Abstract

© 2020 John Wiley & Sons, Ltd. A novel full-wave rectifier (or inverting full-wave rectifier) based on a single second-generation current controlled conveyor (CCCII) having no external passive components and diodes, conducive to IC implementation, is proposed in this paper. The circuits are capable of precisely processing the input signals of up to 30 MHz frequency, while in the situation when the circuits are operating in a voltage mode (VM), the allowed range of possible changes in the input voltage signal is ±500 mV compared with ±1 mA in the current mode (CM). In order to more fully perceive the performance of the proposed full-wave rectifier, the influence of nonidealities and parasitic impedances effects on its work was analyzed. The simulation results using 0.35-μm parameters confirm the feasibility of the proposed solutions.
